THE LAW AND PRACTICE. 

An application for a Patent consists of a Petition, Specifica- 
tion, Oath of Invention, Drawings and a Model. No application will 
be examined by the Patent Office, until all of the above requirements 
are complied with, and the first Government fee has been paid. The 
specification is a written description of the invention, and is required to 
be in such full, clear, concise, and exact terms, as to enable any person 
skilled in the art to which it appertains to make, and use the same. — 
It must be followed by a specific and well defined claim of the part, im- 
provement, or combination which the applicant regards as his invention 
or discovery. In preparing the specifications of an invention, the ut- 
most care and experience is rendered necessary, and as the value of pat- 
ents depend largely upon the manner in which they are drawn; thorough 
scientific and legal attainments are indispensable. Our specification 
writers are men of years of experience in this branch alone ; who have 
a practical acquaintance with the arts and manufactures, combined wiih 
a correct knowledge of the legal force and meaning of technical terms, 
and are in every sense competent to handle any class of invention. 
The Specification must be signed by the inventor, or by his executor or 
administrator, and must be attested by two witnesses. 

The Patent Office has established certain rules governing the 
preparation of all drawings required for applications of patents, and 
unless executed in strict conformity with such rules, the office returns 
the same to applicants. We employ only the best of artists to execute 
our drawings, in the preparation of which, our own experience as pro- 
fessional draughtsmen contributes to a great extent in securing good 
workmanship. In connection with this subject we would call attention 
to the Relief-plates, a print from one of which is shown on first inside 



page. These plates are produced by an application of the helio-type 
process from the official copies made in the U. 8. Patent Office. Any 
inventor or patentee may thus obtain, at a trifling cost, a perfect fac- 
simile engraving from the official drawing of his invention. The plate 
itself is blocked, ready for use, and capable of being worked on any 
printing press, with or without type. We are enabled to furnish these 
jfiates at Six Dollars, each, payable when the order is given. 

A Model will be required in every case where the nature of 
the invention admits of such illustration, except in applications for de- 
sign patents. When the invention is a composition of matter, a speci- 
men of each of the ingredients and the composition, properly marked, 
must accompany the application. 

The model must be neatly and substantially made of durable ma- 
terial, metal being deemed preferable ; and should not in any case be 
more than one foot in length, width, or height. If made of pine or 
other soft wood, it should be painted, stained, or varnished. Glue must 
not be used, but the parts should be so connected as to resist the action 
of heat or moisture. 

A working model is always desirable, in order to enable the Office 
fully and readily to understand the precise operation of the machine. 

Those desiring our services in the preparation and prosecu- 
tion of application for patents should send us their full names and resi- 
dence, the Town, County and State ; also a model of their invention, 
with a description of the parts claimed as being new, tegether with the 
first Government fee of $15. We will then prepare the necessary 
drawings and papers and send to the inventor for his signature and ex- 
ecution. Upon the return of the papers to us, duly executed, we file 
the case in the Patent Office, and give the matter our constant attention 
to final examination. A final Government fee of $20 is payable after 
the Patent has been allowed. Our fee in ordinary cases is usually -S25, 
but in cases requiring much extra time, search, and labor, in their pre- 
paration and prosecution, our fees are necessarily much higher. We en- 
deavor to give each case full and impartial attention, and intend by 
faithful service, and by observing strictly the confidence reposed in us, 
to give satisfaction to our patrons in ail matters relating to our profes- 
sion. 

Applications for Patents are frequently rejected by the Pat- 
ent Office, which, by proper management, would have been allowed, 
and Patents obtained. Some inventors prefer to prepare and prosecute 
their own applications, without the aid of competent and experienced 
counsel ; and when their application is informal, or is met bj^ a refer- 
ence to a prior patent, their application is rejected, a patent is refused, 
and that is, generally the end of it. Again, there are many persons, 
.scattered all over the country, who undertake to obtain patents for in- 
ventors, without having the requisite experience or a proper knowledge 
of the rules of practice before the Patent Office, and consequently if a 
patent is refused upon a reference which could easily be overcome by an 
amendment or disclaimer, or by an argument, they have not the facili- 
ties for examining, in the Patent Office, the references cited by the Ex- 
aminer, nor for making the required alterations or arguments; and the 
result is, that they have to inform their client that his case has been 
"rejected," and that lie cannot obtain a patent. 



We offer to examine, free of charge, all such rejected applications; 
and if, after a careful examination, we find that a patent may be obtain- 
ed, we so inform the applicant, agree upon a fee, contingent upon our 
success, and re-open the case. 

Our efforts in the past in conducting rejected cases to a favorable 
termination, have been attended with greater success than we could 
reasonably anticipate, and our services have been secured in such cases 
by upwards of some thirty other Patent firms located in the states. We 
make this branch of our business a specialty, and would invite corres- 
pondence from inventors, patentees, and other Solicitors in relation to 
such matters. 

A Reissue of Patents is for the purpose of changing the word- 
ing of the specification or claims, in case the patent claims too much, 
or does not fully cover all the novel features actually existing in the 
original model or drawing. Patents issued and assigned prior to July 
8, 1870, may be reissued "by the assignee, but the application for the re- 
issue of patents issued or assigned since that date, must be executed by 
the inventor, if living. New drawings and specifications are required, 
and a Government fee of $30 on application, (no second fee,) also a cer- 
tified copy of abstract of title. 

We will give particular attention to the examination of patents, 
and will give our views as to the propriety of reissuing without extra 
charge. 

A Patent for a design may be granted to any person, whether 
citizen or alien, who has invented or produced any new and original de- 
sign for a manufacture, or any new, useful, and original shape or con- 
figuration of any article of manufacture, the same not having been 
known or used b} r others before his invention or production thereof, up- 
on payment of the duty required by the law, and other due proceedings 
had, the same as in cases of inventions or discoveries. 

Patents for designs are granted for the term of three and one-half 
years, for seven years, or for fourteen years, as the applicant may elect, 
and the Government fees are $10, $15, v and $30, respectively. 

Trade Marks may be obtained for thirty years, by any person 
or firm domiciled in the United States, who are entitled to use of, or in- 
tend to adopt and use, any lawful Trade-Mark. A single word or new 
name, applied to particular goods, as "Beaverine" fortieth, may con- 
stitute a lawful Trade-Mark. 

The right to use any Trade-Mark is assignable b) 7- any instrument 
of writing," and such assignments must be recorded in the Patent Office 
within sixty days after its execution. In order to enable us to register 
a Trade-Mark, the following directions should be carefully observed. 

1. Send the full name, or names, of the party or firm, together 
with the firm-name ; and their several residences and place of business. 

2. State the class of merchandize and particular description of goods 
comprised in such class, by which the Trade-Mark has been or is intend- 
ed to be used. 

3. Send us a description of the Trade-Mark itself, accompanied by 
fac-similes thereof; and state the mode in which it has been or is in- 
tended to be applied or used: 



6 

4. State whether the Trade Mark is already in use, and if so, how 
long it has been used. 

5. Send us twelve copies of the printed Trade-Mark. If none are 
printed, w*e can have photo-lithographic copies made here, at a reason- 
able cost. 

The Government fee for a Trade-Mark is $25. 

Prints and Labels designed to be used upon articles of manu- 
facture can now be registered in the U. S. Patent Office. But no such 
print or lable can be registered unless it properly belong to an article 
of commerce, and be as above defined : nor can the same be registered 
as a print or lable when it amounts in law to a technical Trade- Mark. 

We attend to the registration of any such prints or labels, and have 
the same certified under the seal of the Commissioner of Patents, for a 
fee of $10, which includes Government fees. Applicants should send 
us five copies of the matter desired to be registered. 

Inventors can assign the whole or part of their right to inven- 
tors either before or after the patent issues, and the patent may be made 
to issue to the assignees. We prepare assignments of all kinds, and 
have the same recorded on the books of the United States Patent Office, 
for a fee of $5. 

We also prepare agreements, licenses, and all other papers having 
any relation to patents. 

We make searches of assignments as to validity of patents, vesting 
of titles, reports of infringements, and attend to all other patent busi- 
ness. 

A Copyright can be obtained by any person who is a citizen 
of the United States, or a resident therein, being the author of any 
book, map, chart, or musical composition, and also by the executor, ad- 
ministrator, or assignees of such person. 

The term of the Copyright is twenty-eight years from the time of 
recording the same. 

Our charges for procuring a Copyright are $5, including Govern- 
ment fee. 

Send all remittances by registered letter or money-order ; never en- 
close money with letters or models. 

We invite enquiry at the United States Patent Office as to our 
standing as attorneys. 

The best official and local references sent to those desiring them. 

Any further information relating to the patent business will be 
cheerfully furnished. Address
